RESUMO

Secondhand smoke (SHS) caused by smoking on apartment verandas is a severe social problem in Japan. If someone smokes on a veranda, SHS drifts into other residents' rooms through their windows. Most non-smoking residents are annoyed by this, but they do not confront the person responsible. To study this situation, we burned cigarettes and measured the spread of SHS in terms of fine particle (PM2.5) concentrations. Cigarette smoke generated on a lower veranda spread to upper and horizontal neighboring verandas and into rooms through windows, reaching a maximum concentration of 139 µg/m3. The Health Promotion Act that was revised in 2018 and enacted in 2019-2020 requires all smokers to avoid producing SHS, even outdoors and at home. It is expected that combining the measurement of SHS from verandas to other verandas and rooms with the revised Health Promotion Act could create a national consensus on "no smoking on apartment verandas."

RESUMO

OBJECTIVE: To compare physical activity levels and sedentary behavior between individuals working in the office and those working from home, with the aim of elucidating the potential implications on employees' health. METHODS: We used triaxial accelerometers to assess the physical activity levels of 94 white-collar employees from a large-scale manufacturing company in Japan. They were instructed to wear the accelerometers during their working hours, which included the commuting time on work-in-office days. RESULTS: The mean energy expenditure on work in office was 426 kcal for individuals, while it was 228 kcal on work from home (P < 0.01). In addition, not including commuting, the time spent sedentary on work-from-home days was higher than that on work-in-office days by 20 minutes. CONCLUSIONS: Work from home decreases physical activity and increases sedentary time compared with work in office.

RESUMO

OBJECTIVE: The Health Promotion Act was revised in 2018 and prohibits smoking inside taxis and buses. However, there is no regulation for smoking in the business vehicles of companies or private cars. This paper examined exposure to secondhand smoke in vehicles with digital dust monitors. MATERIAL AND METHODS: A cigarette was smoked inside of a five-seat car, and particulate matter 2.5 (PM2.5) concentrations were measured at front and rear seats. RESULTS: The concentration of PM2.5 reached 3,400 µg/m3 with all windows closed and decreased to approximately 3,000 µg/m3 when driver's window and passengers' windows were opened by 10 cm. However, the PM2.5 concentration did not decrease to levels below 1,500 µg/m3 with all windows fully opened. DISCUSSION AND CONCLUSION: To prevent exposure to secondhand smoke, smoking should not be allowed inside any vehicle when non-smokers are present.
